Sand Fencing

Once a dune is replenished sand fencing provides a barrier to trap sand and continues the replenishing of the dunes. “Sand fences” create areas of lower wind speed both in front of and behind the fence encouraging sand deposition. The amount of sand trapped depends on the fence height, the size of spaces between fence slats, and wind speed. Wooden slat fences are most commonly used.


Over half of our existing sand fencing was partially or fully destroyed during the winter of 2019. Sand fencing was restored where it could be from Ozone to Sail.  We will continue to offer additional sand fencing to oceanfront owners for private use and help with our KEEP OFF DUNE campaign.
